The APEX Gyro Sonde
The Geovista APEX Gyro Sonde is a Three-axis Micro-Electromechanical System (MEMS) device that measures borehole trajectory data. The APEX is a Continous All Angle North Seeking Gyro sonde. It can be run in both wireline and memory modes.
Status Q4 2025: Prototype and field trials. Get in touch for early partnership opportunities.
The Apex Gyro is also a key product in our Driller Operated suite of technologies.
Geovista is ISO 9001:2015 compliant. All of our equipment is pressure and temperature tested and undergoes a complete QC procedure.
The APEX Gyro: Your Next-Generation Borehole Survey Tool.
-
The Geovista APEX Gyro Sonde provides fast, continuous, orientation and deviation surveys of boreholes in any environment, including steel casing and drill pipe. Crucially, it can measure in all directions and inclinations. It is highly accurate, and does not require any field calibration.
-
The GV APEX Gyro can also be combined with other Geovista Sondes like the Gamma Ray, for example. It is available for operation in two modes:
-
Real-Time: Runs on an E-Line and provides real-time trajectory data.
-
Memory: Runs on a slick-line and stores data in memory that can be downloaded once the sonde is back at the surface.
